To achieve a signal addressee, must be inserted into the core rays at an angle to the lateral surface is not less critical. In this case, the effect of full reflection is realized, and theoretically the beam never leaves the core except through the end of fiber. However, in practice, there is a certain percentage of refracted rays. This is due firstly with the complexity of the implementation of such a light source, and secondly with the inability to manufacture perfectly smooth fibers, and thirdly of the non-ideal optical cable installation.<br>The fiber is made of quartz, which is the basis of dioxide silicon, widespread, but because the inexpensive material, in contrast to copper, hence the relatively high price and almost no cases of theft for the purpose of putting up for scrap.
